Rear air shocks went out and noticed leveling compressor was not coming on. I replaced air shocks and leveling compressor still not coming on. I checked fuses and fuse four and fifteen were blown replaced fifteen but when out new fuse in four sparks and blows.

A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a twelve volt light bulb. A brake light bulb works well. When the circuit is live and the short is present, the bulb will be full brightness and hot so be sure it is not laying on the carpet or against a plastic door panel. Now you can unplug electrical connectors and move things around to see what makes the short go away. When it does, the bulb will get dim or go out.
